Abstract (en)
A method for preparing an ink-jet ink set comprising the steps of: (a) preparing a first colour ink by mixing a polymeric dispersant and a pigment having a maximum absorbance A max between 400 and 500 nm and an absorbance A ref at a reference wavelength of 600 nm; (b) preparing a second colour ink by mixing a polymeric dispersant and a pigment having a maximum absorbance A max between 500 and 600 nm and an absorbance A ref at a reference wavelength of 650 nm; (c) preparing a third colour ink by mixing a polymeric dispersant and a pigment having a maximum absorbance A max between 600 and 700 nm and an absorbance A ref at a reference wavelength of 830 nm; characterized in that each colour ink is milled until a spectral separation factor SSF larger than 70 with SSF = A max / A ref is measured. An ink-jet ink set obtainable by the above method is also disclosed.
